Subject: [PATCH net-next 2/3] selftest: Fix set of ping_group_range in fcnal-test

From: David Ahern <[email-masked]>
Date: Wed, 24 Jan 2024 14:41:16 -0700

ping_group_range sysctl has a compound value which does not go
through the various function layers in tact. Create a helper
function to bypass the layers and correctly set the value.
